l Ld l l l QW-MW@ @f Wynne/t3 To all 'whoni it may concern: Beitknown that I', ELI'SHA A. CONWAY, a

citizen of the United States, residing 'at Parkesburg, in the .county of Chester and State of- Pennsylvania, have invented cer-A n tain' new'and usefullmprovements in Razor.-

Sharpening Machines, of which the follow-' in 1s a specification.

yinvention relates to an improved razor -sharpening machine, anlobyectof the invenj. tionbeing to provide an improved machine stropping.'

A irther object is to provide an -improved' hone with an improvedv strop, which latter' may be secured on the hone, wlien'the'ma# 2'5 chine is to be used for stro ping. l

With these and other o bJects in view, the' invention consists in certain novel featuresy of construction and combination and iarrangements of parts as will-be more lfully 30 hereinafter described'aiid pointed out inthe G5 claims.
